Porous materials containing salts may undergo swelling by fresh water uptake induced by osmotic flows. A constitutive model including creep is adopted in order to describe the mechanical behavior of such a material. A formulation is proposed for the analysis of deformation induced by dissolution of salts due to water uptake. The formulation includes some aspects which are particular for Eurobitum but it can be applied to soils and rocks to investigate a similar response which is probable in low permeability geological materials.
